Add a NuttX ADC lower-half for the Ameba SoC family, wired for the
amebadplus/pke8721daf as /dev/adc0. The driver uses the fwlib ROM
API and drives on-demand polled conversions via ADC_ReceiveBuf with
the hardware auto channel-switch FIFO, because amebadplus disables the
ADC software-trigger path. Per-chip wiring (channel count, pinmux
function id, APB clock bits, optional aux clock) lives in a chip
header so a new IC only supplies its own values without touching the
shared driver.
Reports raw conversion codes per the NuttX convention (12-bit
effective, 0..~3876 for 0..3.3V), consistent with the STM32/i.MXRT/
Tiva ADC drivers.
Verified on hardware: 0V->121, 3.3V->3876 on CH0(PB19) while
CH1(PB18) held steady, confirming sampling, full-scale and
multi-channel switch-list isolation.

Add initial Apache NuttX support for the Allwinner D1 / T-Head C906
running in supervisor mode under OpenSBI.
Add support for:
- RV64 D1 architecture definitions
- Lichee RV 86 Panel board configuration
- UART0 console at 115200 baud
- D1 PLIC interrupt controller
- native D1 Timer1 scheduler tick
- early inherited-watchdog disable
- FLAT S-mode NSH configuration
The port has been tested on physical Sipeed Lichee RV / 86 Panel
hardware and boots to an interactive NuttShell.
The scheduler tick uses OSC24M Timer1 at 1000 Hz. The Timer1 interval

ESWIN's own evaluation board for this SoC. Where the StarPro64 is a
single board computer built around the chip, the EVB brings out most of
the SoC's interfaces.
Everything shared with the StarPro64 is already in the common directory,
so this carries the board's own facts: which UART reaches which connector,
which pads carry the boot straps, where its memory sits, and a
configuration starting from the same place the StarPro64's does.
The summary tables on sheet 3 of both boards' schematics are inherited
from ESWIN's reference design and describe that design rather than either
board. On this board the console is UART0 through the FT4232 bridge,
UART1 goes to the M.2 socket and a header, and UART2 reaches the RS232
port.
The documentation page follows the board template: a photograph, the
board's features, the console and its port on the FT4232 bridge, power,
the build and TFTP boot procedure, and what NuttX drives so far.
Boots to an NSH prompt over UART0 with all four harts running.

The port had one board directory holding one board, with everything in it
whether it described the SoC or the PCB. A second EIC7700X board follows,
so this adopts the common-plus-board layout NuttX provides, as mpfs uses.
boards/risc-v/eic7700x/common holds what is true of the SoC: the boot path
that mounts the RAM disk and /proc before calling the board's own bring
up, the linker script, the start up scripts and the image builder.
ARCH_CHIP_EIC7700X selects ARCH_BOARD_COMMON, so the symlinks the build
makes always point at code that compiles.
The board directory keeps what is a fact about the PCB: its own board.h
and board_memorymap.h, since the include fallback is all or nothing, a
bring up that owns the order its devices register in, and a board_config.h
declaring what that bring up may call.
The image builder moves to common/tools and derives its output name from
the configuration. It computes the padding between the kernel and the RAM
disk from _ebss rather than assuming 64 KiB, which fails once BSS grows
past it: the disk lands below _ebss and the BSS clear zeroes it before
anything searches for it.
The StarPro64 configuration gains what the port now needs: four harts,
960 MiB of RAM, a larger task stack, a backtrace on assert, the system log
in RAM for dmesg, and ELF applications, for which ARCH_CHIP_EIC7700X now
selects ARCH_HAVE_ELF_EXECUTABLE.
board.h loses its LED definitions. CONFIG_ARCH_LEDS is not set, nothing
implements board_autoled_on(), and the indices they gave named no LED.
The documentation pages gain the tags the template asks for.

Add a shared NuttX PWM lower-half for the Realtek Ameba PWM timer in
arch/arm/src/common/ameba, driven through the SDK fwlib. TIM8 provides a
single time base feeding eight compare channels (CCR0..CCR7) that share one
frequency while each carries its own duty, so a single /dev/pwm0 exposes the
multichannel output via CONFIG_PWM_NCHANNELS. The fwlib PWM routines are
split ROM/RAM: the time-base calls resolve from on-chip ROM, while the
capture/compare calls live in fwlib ram_common/ameba_tim.c, which the build
pulls into AMEBA_FWLIB_SRCS when CONFIG_AMEBA_PWM is set.
Per-chip wiring (timer index, channel count, register base, input clock,
IRQ, clock masks and the crossbar pad-mux code table) lives in
arch/arm/src/rtl8721dx/ameba_pwm_chip.h so a port to another Ameba chip only
supplies a same-named header; the pad-mux codes are a per-channel table
(AMEBA_PWM_PINMUX_FIDS) rather than a computed base, so chips with a single
shared code or codes grouped per timer are expressed by the header alone.
The timer registers as /dev/pwm0 from pke8721daf bring-up through the stock
PWM character driver; a dedicated `pwm` defconfig drives examples/pwm for
validation.

from the requested frequency, outside its own bandwidth.
- The low or high frequency front end was left at its reset value, so a board

- sx127x_rx_watchdog() is only used by the FSK and OOK path but was compiled
